N2 - Variability in soil moisture on a steep slope near a ridge in a forested mountain range, Shikoku, Japan, was studied observationally and numerically. Vertically integrated soil moisture, from a depth of -60 cm to the surface, W, was introduced as a key indicator, and its seasonal variation was analysed on a daily basis from August 2011 to August 2012. The "bucket with a bottom hole" (BBH) model of Teshima et al. (2006) was improved to consider the forest environment in simulating the variation in W. A "big-leaf" model was incorporated into the modified BBH model to estimate transpiration and interception by trees. The simulated soil moisture agreed reasonably with observed values on a daily to inter-seasonal timescale.
